The filter of the kettle is made of high-quality stainless steel, which means that it is not made of plastic. However, this information refers to general filters for De'Longhi kettles and not specifically to the KBOV 2001.BG model.
Hello
The product is 99% stainless steel, the only internal part made of plastic is the filter frame, which is in the upper part where you pour the water.
By the way, you can take it out.
The product may have a foreign power plug, which can be connected to Swiss sockets by means of an adapter supplied.
This is an older model which is currently still available from our supplier.
